SPECIFICATION forming part of Letters Patent No. 639,171, dated December12, 1899.

Application filed April 17, 1899. Serial No. 713,335. (No model.)

To all whom t may concern:

Beit known that I, ALBERT E. GREEN, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Oultivators,ofwhich the following is a specification.

The object of this invention is to construct a cultivator in which aframe supporting teeth is given a reciprocating movement and also amovement transverse to its reciprocating movement.

In the accom an ino" drawings Fi'nre 1 is D b 2 D a plan View of acultivator embodying my improvements. Fig. 2 is a vertical lengthwisecentral section. Fig. 3 is a front elevation of one-half of thecultiva-tor. Fig. 4 is an isometrical representation of the drag-bar andattachments. Fig. 5 is an isometrical representation of thelifting-lever.

The main frame consists of the transverse bar 1, from which depend bars2 and 3. Lengthwise bars 4 connect with the bars 2. lVheels 5 aresupported upon stub-axles 6, secured to the lengthwise bar 4, and to theinner face of each of the wheels is secured a groovefaced Wheel 7.

A stationary shaft or support 8 extends transverse of the main frameandis connected with the lengthwise bars 4. A drivers seat 9 issupported by the bars 10, pivotally connected to the short bars 11,which are pivotally connected to the lengthwise bars 4 of the mainframe. The supporting-bars for the seat rest upon the stationary support8, and by means of the pivoted short bars 1l the seat can be adjustedforward or backward, and, if necessary, the short bars can be placed onthe upper surface of the lengthwise bars 4, which will depress the seatand bring it nearer the drag-bar.

A. bracket is secured to the inner face of the depending-bars 2 and 3,and consists of the tubular section 12, vertical portion 13, and ibranches 14. A shaft 15 is located in the tubular section, and to oneend is secured a grooved wheel16,and to its other end is secured acrank- 1head 17, having a wrist-pin 18. A belt 19 connects thegroove-faced pulleys 7 and 16, and the rotary movement of thecarrying-wheel will impart a rot-ary movement to the crankhead.

A drag-bar 2O of rectangular form has a pivotal connection with a head2l, which in turn has a pivotal connection with the depending bar 3, soas to move in a horizontal plane, while the pivotal connection of thedrag-bar with the head permits the drag-bar to move in a vertical plane.

The drag-bar supports a frame 22, having a lengthwise opening 23 in itsupper tace, and its under surface supports teeth 24. A plate 25. issecured to the upper surface of the forward end of the frame, and a pin2G projects from its upper surface. To this plate is pivoted a plate 27,its forward end having a cutaway portion 28 and its rear end supportinga block 29, pivoted thereto upon the vertical stud 30. A pitman 3l has apivotal connection with the crank-head 17 anda pivotal connection withthe block 29 upon a horizontal stud 32. (Shown in dott-ed lines, Fig.2.) As the crank-head is rotated the pitman will impart a reciprocatingmovement to the frame in the lengthwise direction of the drag-bar, andthe various pivotal connections permit the drag-bar to be movedhorizontally without moving the pitman laterally.

A shovel 33 is"snpported by the drag-bar in rear of the reciprocatingframe, and,if deemed necessary, others may be supported in advance ofthe frame and serve to hill the corn.

Av frame composed of the lengthwise bars 34 and cross-bars 35 is pivotedupon the stationary shaft 3, the ends of the bar 34 in advance of theshaft supporting lifting-levers, a detached view being shown at Fig. 5,in which a segment 36is secured to the bar, and a grooved wheel 37 ispivoted upon astud 38, extending from the bar. This toothed wheelsupports a hand-lever 39 in a pivotal manner, and a coiled spring 40surrounds the lever, one end connected to the grooved Wheel and itsother end connected to the projection 41, extending from the lever. Anarm 42 extends from the lever at its upper end, by means of which thegrooved Wheel is moved.

To the depending bar 3 is secured a bracket 43, its free end pivotallysupport-ing abar 44. The rear end of the bar supports a roller 45.

IOO

A screw-threaded rod 4G passes through the transverse bar l and engagesthe forward end of the bar 44. A iexible connection 47 is secured to thegrooved wheel 37, passes over the roller 45, and is secured to thedrag-bar 20.

By means of the frame pivoted upon the rod S and its connection withboth drag-bars the attendant in the seat can, with his feet, depress therear end of the frame, which will raise the grooved rollers 37, therebyraising both drag-bars. The depth at which the teeth work in the groundmay be regulated by the hand-lever 39 in con nection with the toothedsegment 36, and a iner adjustment may be had by means of thescrew-threaded rod 4G. The projection 4l of the hand-lever will engagethe teeth of the segment, and by a movement rearward of the arm 42 thehand-lever Will be oscillated, which will disengage the projection fromthe toothed segment.

Byimparting a reciprocating movement to the frame the teeth supportedthereby Will scratch the ground and destroy the weeds.

It is evident that sprocket-wheels and a linked chain may be employed todrive the crank-head.

In the horizontal movements of the dragbar the ends of the cutawayportion 2S will come in contact with the pin 26, thereby limiting itsmovement.

I claim as my inventionl. The combination of a main frame, sup

porting-wheels, a drag-bar, a frame supported by the drag-bar, meansforminga connection between the wheels and frame wherebya reciprocatingmovement is imparted to the frame, the frame supporting teeth, a stoplimiting the horizontal movement of the drag-bar.

2. The combination of a main frame, supporting-wheels, a drag-bar, aframe supported by the drag-bar, means forming a connection between thewheels and frame whereby a reciprocating movement is imparted to theframe, the frame supporting teeth and the drag-bar a shovel.

3. The combination of a main frame, supportingwheels, a drag-bar, ahand-lever, a llexible connection between the hand-lever and drag-bar,and means operating upon the Iiexible connection as means additional tothe hand-lever for adjusting the drag-bar.

4. The combination of a main frame, supportingwheels, a drag-bar, ahand-lever adjusting the drag-bar, consisting of a saW- toothedseg1nent,apivoted lever, a projection extending from the lever engagingthe segment, a spring holding the projection in engagement with thesegment and a grooved curved surface connected with the lever.
